Phylogeny And Floral Character Evolution Of Mentzelia Section Bicuspidaria (Loasaceae), Joshua M. Brokaw, John J. Schenk, Jessica K. Devitt, Destiny J. Brokaw

Biology

Mentzelia section Bicuspidaria (Loasaceae) is a monophyletic group of desert ephemerals that inhabit the complex, heterogeneous landscapes of the southwestern United States and northwestern Mexico. To investigate species circumscriptions and evolutionary relationships in M. sect. Bicuspidaria, we employed phylogeny reconstructions based on DNA sequences from the plastid trnL-trnF, trnS-trnfM, ndhF-rpl32, and rpl32-trnL regions and the nuclear ribosomal ITS and ETS regions. Due to evidence of discordant relationships reconstructed from the plastid and nuclear partitions, we used coalescent-based methods in addition to concatenated data sets to estimate the species tree. Maximum likelihood reconstructions based on the combined …


Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi May 2020

Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi

Honors Theses

Household/commercial bleach (6% NaOCl, sodium hypochlorite) degrades DNA through oxidative damage, production of chlorinated base products, and cleavage of DNA strands (breaking it into smaller and smaller fragments). The presence of these lesions significantly impacts the ability to generate a full genetic profile from an evidentiary sample. In fact, knowledge of the damaging effect of bleach on DNA is the basis for its use in forensic laboratories to clean workbenches and prevent cross-contamination of samples between cases. Additionally, bleach is used intentionally by criminals to clean up crime scenes and destroy DNA evidence. A previous study demonstrated that bleach has …


The Small Heat Shock Protein Αb-Crystallin Is Critical To Cell Survival In Response To The Phytochemical Withaferin A In Cisplatin-Resistant Ovarian Cancer Cells, Melissa Carmichael May 2020

The Small Heat Shock Protein Αb-Crystallin Is Critical To Cell Survival In Response To The Phytochemical Withaferin A In Cisplatin-Resistant Ovarian Cancer Cells, Melissa Carmichael

Honors Program Theses and Projects

Withaferin A (WA), the active-phytochemical of the medicinal plant Withania somnifera, promotes apoptosis in cancer cells. Although its mechanism remains unclear, WA has been shown to upregulate heat shock proteins (Hsps) which protect against diverse cellular insults. The small Hsps, αB-Crystallin and Hsp27, confer resistance to chemotherapy in several cancer cell lines, however, the role of WA on αB-Crystallin and Hsp27 expression in drug resistance remains unknown. Since the majority of ovarian tumors eventually recur in a drug-resistant form leaving patients few treatment options, the goal of this study is to explore the molecular mechanism induced by WA in a …


Molecular Properties Are A Primary Control On The Microbial Utilization Of Dissolved Organic Matter In The Ocean, Yuan Shen, Ronald Benner May 2020

Molecular Properties Are A Primary Control On The Microbial Utilization Of Dissolved Organic Matter In The Ocean, Yuan Shen, Ronald Benner

Faculty Publications

The global ocean sequesters a large amount of reduced carbon in dissolved organic molecules that can persist for centuries to millennia. The persistence of dissolved organic carbon (DOC) in the deep ocean has been attributed to inherently refractory molecules and to low concentrations of molecules, but the relative roles of molecular properties and molecular concentrations remain uncertain. We investigate both of these possibilities using bioas-say experiments with unfiltered seawater collected from five depths (50–1500 m) at the Bermuda Atlantic Time-Series Study site. The microbial utilization of compositionally distinct forms of seawater DOC at in situ and elevated concentrations was determined. …

Effect Of Fire Suppression On Aquatic Invertebrates In Ephemeral Wetlands Embedded In Longleaf Pine Forests, Hailey E. Baker May 2020

Effect Of Fire Suppression On Aquatic Invertebrates In Ephemeral Wetlands Embedded In Longleaf Pine Forests, Hailey E. Baker

Honors College Theses

It has been established for many years that longleaf pine forests require the ecological disturbance of fire in order to maintain a balanced ecosystem. However, a crucial part of these forests has become nearly excluded from prescribed burning. Ephemeral wetlands embedded within longleaf pine forests are a unique and dynamic seasonal habitat that provide homes, refuge, and breeding grounds for a large array of taxa. Past research suggests that fire suppression around ephemeral wetlands is causing harm to many species of amphibians and other herpetofauna, especially threatened species like the flatwoods salamander. However, other species have not been as well …


Comparative Study Of Spectral Sensitivity, Irradiance Sensitivity, Spatial Resolution And Temporal Resolution In The Visual Systems Of Aratus Pisonii And Ocypode Quadrata, Ruchao Qian May 2020

Comparative Study Of Spectral Sensitivity, Irradiance Sensitivity, Spatial Resolution And Temporal Resolution In The Visual Systems Of Aratus Pisonii And Ocypode Quadrata, Ruchao Qian

All HCAS Student Capstones, Theses, and Dissertations

Autrum’s studies (1950, 1958) on terrestrial arthropods first revealed that the visual systems of arthropods reflected their lifestyles and habitats, demonstrating that rapidly moving predatory diurnal species tend to have better temporal resolution than slower moving nocturnal species. In order to test Autrum’s hypothesis that visual adaptions are driven by predator/prey interactions, the visual physiology of a nocturnal fast-moving predatory crab, the Atlantic ghost crab (Ocypode quadrata), and a diurnal herbivorous crab, the mangrove tree crab (Aratus pisonii), was examined and compared. Spectral sensitivity, irradiance sensitivity, and temporal resolution of the crabs were quantified using the …

Alverdy

Biology Faculty Publications

Death due to sepsis remains a persistent threat to critically ill patients confined to the intensive care unit and is characterized by colonization with multi-drug-resistant healthcare-associated pathogens. Here we report that sepsis in mice caused by a defined four-member pathogen community isolated from a patient with lethal sepsis is associated with the systemic suppression of key elements of the host transcriptome required for pathogen clearance and decreased butyrate expression. More specifically, these pathogens directly suppress interferon regulatory factor 3. Fecal microbiota transplant (FMT) reverses the course of otherwise lethal sepsis by enhancing pathogen clearance via the restoration of host immunity …


Sexually Dimorphic Alterations In Brain Morphology Of Astrocyte Conditional System Xc- Knockout Mice, Gabrielle Emily Samulewicz May 2020

Sexually Dimorphic Alterations In Brain Morphology Of Astrocyte Conditional System Xc- Knockout Mice, Gabrielle Emily Samulewicz

Biology - All Scholarship

Astrocytes play a vital role in orchestrating the precise brain wiring that occurs during development and are essential for maintaining homeostasis into adulthood. The cystine/glutamate antiporter, system xc-, in the central nervous system is especially abundant in astrocytes and itself is known to contribute importantly to the basal extracellular glutamate concentration as well as the intracellular and extracellular glutathione levels, either of which, if perturbed, could alter brain development and/or contribute to degeneration. Thus, to determine whether loss of astrocyte system xc- might alter brain morphology, I studied a conditional astrocyte system xc- knockout mouse (AcKO). Tissue was harvested from …

Identifying Determinants Of Target Specificity In Two Related Bacterial Peptide Toxins, Andrew D. Holmes May 2020

Identifying Determinants Of Target Specificity In Two Related Bacterial Peptide Toxins, Andrew D. Holmes

Honors Thesis

Toxin-antitoxin (TA) systems were originally identified as two-component systems ensuring the stable inheritance of plasmids in bacterial populations. Recently, they have been identified on bacterial chromosomes where their functions remain mostly undefined. The par locus of E. faecalis plasmid pAD1 (parpAD1) was the first TA system defined in a Gram-positive bacterium and a homolog encoded on the E. faecalis chromosome (parEF0409) was later described. Related loci numbering in the hundreds have been identified throughout Gram-positive bacteria based on homology to the toxin of the system, Fst, and similarities in genetic organization and regulation. Despite …


The Relationship Between Glucocorticoids And The Humoral Immune Response To Mycoplasma Gallisepticum Challenges In Eastern Bluebirds, Joshua Smith May 2020

The Relationship Between Glucocorticoids And The Humoral Immune Response To Mycoplasma Gallisepticum Challenges In Eastern Bluebirds, Joshua Smith

Honors Theses

Numerous studies have examined relationships between adrenal glucocorticoids and the immune system’s ability to fight disease. The relationship can vary, with glucocorticoids having either stimulatory or inhibitory effects. The pathogenic bacterium Mycoplasma gallisepticum (MG) elicits an adaptive immune response in birds, in which B cells produce MG-specific antibodies to fight the infection and prevent reoccurrence. Previous research found that Eastern Bluebirds that produce the most antibodies in response to MG infection also have the highest glucocorticoid levels. This finding led to the current study investigating whether corticosterone, the primary glucocorticoid in birds, stimulates production of antibodies in response to immune …

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt May 2020

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt

Honors Thesis

The fungal pathogen Batrochochytrium dendrobatidis (Bd) has been threatening amphibian populations across the globe. Recent work has discovered that bacteria isolated from certain populations of amphibians protect hosts from this pathogen. This project focuses on the anti-fungal mechanisms of Serratia marcescens, a species of bacteria isolated from a Costa Rican frog that dramatically inhibited Bd in culture. Wild-type and recombinant S. marcescens was introduced to the microbiomes of a live amphibian host, Acris blanchardi (Blanchard’s Cricket Frog) and then challenged with Bd to examine the protective effects of this bacteria. The experiment includes recombinant S. marcescens with …


Ectomycorrhizal Fungi And Effects Of Soil Microbes Associated With Slash Pine Encroachment Into Native Longleaf Pine Habitat, Madison Brooke Woodruff May 2020

Ectomycorrhizal Fungi And Effects Of Soil Microbes Associated With Slash Pine Encroachment Into Native Longleaf Pine Habitat, Madison Brooke Woodruff

Honors Theses

Biological invasions can cause substantial changes to the environment: indigenous species can be reduced or even eliminated, soil characteristics shifted, and nutrient cycles altered. Ectomycorrhizal (ECM) fungi are thought to be key biological controllers of some plant invasions, especially benefiting Pinus species in invasions at exotic sites, but less is understood about the role of ECM fungi and other soil microbes in encroachment by one plant species into the habitat of another in their native ranges. In this study, soil was collected from three habitats in southern Mississippi, USA: native slash pine maritime forest, longleaf pine savanna encroached by slash …


Population Genetics Of A Recent Range Expansion By The Southern Pine Beetle, Dendroctonus Frontalis, Into The Northeastern United States, Megan Stubbs May 2020

Population Genetics Of A Recent Range Expansion By The Southern Pine Beetle, Dendroctonus Frontalis, Into The Northeastern United States, Megan Stubbs

Honors Theses

Population genetics as a field of study aims to determine the genetic variation among individuals in a population, and differences among populations. Certain population genetic analyses can provide such information and be used to better understand the biological aspects to a species’ expansion beyond its native range. The southern pine beetle (SPB), Dendroctonus frontalis, has become an invasive pest to pine forests in northeastern United States with its recent range expansion. Nine microsatellite loci were first developed and then used in analyses. To determine what the genetic variation is among individuals in SPB populations across its entire range, including …

The Trichoplusia Ni Gut Microbiome And Its Derivation From The Phyllosphere Of Its Food Plants, Josemaria Garcia, Marisol Escanuela, Swapna Bhat, Evan Lampert

Georgia Journal of Science

Insects are the most abundant and diverse animals on planet Earth and rely on their diverse microbiomes to be so. The insect gut microbiome is vital in the growth and development of many insect species. Trichoplusia ni, the cabbage looper, is a generalist herbivore, but little is known about its microbiome. In this study, a metagenomic analysis of fecal samples was used to determine the effect of diet on the microbiome of T. ni larvae. Larvae were reared on six plant species, the microbiome was sampled from fecal material, and the phyllosphere was sampled from leaves the larvae ate. …

Testing The Potential Of Environmental Dna: Genetic Monitoring Of Estuarine And Coastal Bottlenose Dolphin (Tursiops Truncatus) Stocks In South Carolina, Kathryn Greiner-Ferris

Electronic Theses and Dissertations

Environmental DNA (eDNA) analysis is a non-invasive monitoring technique that can detect and potentially monitor elusive marine mammals. To date, the majority of eDNA studies have been performed in freshwater environments, partially due to methodological challenges posed by higher salinities and increased dilution effects of large water masses in marine environments. The objective of this study was to design and optimize species-specific oligonucleotide PCR primers to accurately detect and quantify common bottlenose dolphin (Tursiops truncatus) eDNA collected from the marine environment and to evaluate potential trends between eDNA concentration and dolphin abundance and seasonality. Primer pairs were designed to target …


Novel Method To Determine Paleodiet Of Extinct Equid Merychippus Sp. Using Dental Calculus, Ranjit Z. S. Virk May 2020

Novel Method To Determine Paleodiet Of Extinct Equid Merychippus Sp. Using Dental Calculus, Ranjit Z. S. Virk

Senior Honors Projects, 2020-current

Within the Miocene Epoch, the emergence of grasslands within North America coincided with the incidence of higher-crowned teeth (hypsodonty) within the proto-horse Merychippus that allowed for the inclusion of these expanding grasslands as a food source. As herbivorous paleofauna consume plant matter, microscopic remains become incorporated within dental calculus and, due to their diagnostic morphology, can be used to identify dietary components. In Merychippus, the recovery of plant microfossils holds the potential to provide greater clarity on the paleodiet of these equids. In the present study, the purpose was to quantify and compare Merychippus paleodiet constituents among sample groups. …


Characterizing The Role Of Β-Amylase3 In Cold Stress Response And Recovery In Arabidopsis Thaliana, Isabelle G. Houston May 2020

Characterizing The Role Of Β-Amylase3 In Cold Stress Response And Recovery In Arabidopsis Thaliana, Isabelle G. Houston

Senior Honors Projects, 2020-current

Starch is a polymer of glucose that is used as an energy store in plants. Mobilization of starch has implications in abiotic stress survival and recovery. While the importance of carbon and energy allocation in plant survival has been explored, the specific roles of starch degrading enzymes in plant responses to stress are still unclear. β-Amylase3, or BAM3, is the principle starch degrading enzyme at night and is transcriptionally upregulated in response to cold stress in the plant Arabidopsis thaliana. Using single and quadruple knockout mutant plants, I aimed to clarify the role of BAM3 in the response to …


D-Glucose-6-Phosphate Stimulates Sags-Dependent Biofilm Formation In Pseudomonas Aeruginosa, Madison Gowett May 2020

D-Glucose-6-Phosphate Stimulates Sags-Dependent Biofilm Formation In Pseudomonas Aeruginosa, Madison Gowett

Undergraduate Honors Theses

The SagS protein is a two-component regulatory system in Pseudomonas aeruginosa that works to independently regulate biofilm formation and antibiotic tolerance. Previous work found that these two pathways are controlled by two distinct sets of amino acids within the sensory domain of SagS that are thought to be potential ligand binding sites. Despite the extensive research done on the structure and function of SagS, the signals that activate this protein have yet to be identified. In this study we aimed to identify ligands that stimulate SagS-dependent biofilm formation. To do this we utilized ΔsagS mutants, one harboring wild-type sagS under …


Effects Of Invasion By Plants And Beetles On Roots And Mycorrhizal Fungi Of Plantation Scots Pines In Poland, Meghan M. Van May 2020

Effects Of Invasion By Plants And Beetles On Roots And Mycorrhizal Fungi Of Plantation Scots Pines In Poland, Meghan M. Van

Honors Theses

Biological invasions can cause significant changes to the environment in which they occur. One of the main changes that is caused is how invasive species can disrupt mutualisms between native species in ecosystems. The mutualism between mycorrhizal fungi and plants is one of the most important mutualisms that a plant forms. This mutualism is very important because it is the source of many nutrients that the plant needs. This study took place in a Scots pine (Pinus sylvestris) plantation in northeastern Poland, and aimed to determine the effects of plant and beetle invaders on ectomycorrhizal (ECM) fungi and …


Assessment Of Oral Motor Activity Variables During Consumption Of Chocolate Using Surface Electromyography: Effects Of Variation In Cocoa Solid Content, Kara Elizabeth Cook May 2020

Assessment Of Oral Motor Activity Variables During Consumption Of Chocolate Using Surface Electromyography: Effects Of Variation In Cocoa Solid Content, Kara Elizabeth Cook

Honors Theses

The aim of this experiment is to assess how a wide range of cocoa content in different types of chocolate samples effects oral motor activity for mastication events, along with the time between consumption and swallowing. A prior study assessed individual oral motor activity using surface electromyography (sEMG) for mastication events while eating four different chocolate samples, and this information was used to determine which aspects of the masticatory process underlie differences in individual chewing behavior as well as whether subjects retain their general characteristic eating behavior across a variety of chocolate samples. The study found that with chocolate samples …


A Genomic Analysis Of Bobcat Populations In North America With A Comparison To The Canada Lynx: An Assessment Of Local Adaptation To Unique Ecoregions And Phylogeography, Jennifer C. Broderick May 2020

A Genomic Analysis Of Bobcat Populations In North America With A Comparison To The Canada Lynx: An Assessment Of Local Adaptation To Unique Ecoregions And Phylogeography, Jennifer C. Broderick

Electronic Theses and Dissertations

Bobcats (Lynx rufus) are an ecologically and genetically diverse species with a large contiguous range throughout North America. The species not only has a wide array of phenotypic variation compared to other mammals, but shows marked adaptability across ecozones with differing ecological influences. It is these various selective pressures in distinctive parts of the continent that have likely led to localized adaptations within the bobcat metapopulations. The species is also marked by its ability to maintain connectivity and populations in anthropogenically developed areas, an advantage it has over other felids, including its close relative the Canada lynx ( …
